HERMANN RUDOLPH WOLFF, OF GOEBENG, JAVA.

CENTRIFUGAL MACHINE.

PECIFICATION forming part of Letters Patent No. 7 12,628, dated November4, 1902. Application filed February 11, 1902 Serial No. 93,554. (Nomodel.)

To a wlwnt it may concern:

Be it known that I, HERMANN RUDOLPH WOLFE, a citizen of Germany,residing at Goebeng, Sourabaya, Java, have invented certain new anduseful Improvementsin Centrifugal Machines, (for which application forpatent has been made in Great Britain, No.

16,691, dated August 20, 1901,) of which the following is aspecification.

This invention relates to centrifugal machines for drying sugar; and ithas for its object to provide a door at the bottom of the basket of acentrifugal which can be readily opened to discharge the contents of thehasket.

The invention is illustrated by the accompanying drawings, in whichFigure 1 is a vertical section of a top-driven centrifugal machine ofimproved pattern; and Fig.2, a section, to a larger scale, of theimproved discharge-door.

In the bottom ofthe basket f of the centrifugal, which is usedfor'drying sugar or other granular substance, a discharge-door 25 p, asshown particularly at Fig.2, is provided and is held in closed positionover the dooropeningq by means ofsprings or spring-blades 4", extendingdownward and outward to engage with catches or projections s on theunder side of the basket f. For opening the door 19 a hand-lever t isprovided, which projects upward into the basketf and which on beingtilted by hand withdraws one or more of the springs 1" out of engagementwith the catches, so that the door 13 can be opened to discharge thecontents of the basket f.

Having now described the invention,what I claim, and desire to secure byLetters Patent, is

In a centrifugal machine, the combination with the basket of adischarge-door having spring-blades extending outward to engage catcheson the outside of the basket, and a hand-lever for withdrawing one ofthe springs out of engagement with the catches.

In witness whereof Ihave hereunto set my hand in presence of twowitnesses.

HERMANN RUDOLPH WOLFF.
